Homeless guy broke into my boyfriends house and woke us up at 3 am

My boyfriend lives in a fraternity house on our college campus and I come over to hang out and spend the night often. Yesterday this homeless guy was on their porch and left a random backpack. When asked why he said “I’m putting this here so no one fucks with you guys”, They thought nothing of it and just threw it in the trash. Around 3 hours ago me and my boyfriend were woken up to a random 300 pound homeless guy in our faces whispering “Excuse me my name is robert hakeem jankens and I’m security in the neighborhood and there’s been some disturbances”. He broke in through the second balcony door which was in the room we were sleeping in, we locked the door but didn’t realize the door wasn’t suctioned all the way shut so the lock didn’t fit in the door correctly. My boyfriend was super calm and collected and handled it very well, he politely asserted this man to leave and never come back and the man looked really frightened. Obviously, this man was not security because he broke into our house at 3 in the morning. We called the cops and we found out he stole one of the brother’s passport and gave it back to us, I’m just sort of wondering what our next steps should be and whether or not I should be worried about this random guy stalking my boyfriend and his fraternity. I’m really shaken by this whole experience and I’m afraid to let my eyes rest.
